Cougar response to roads and predatory behaviour in southwestern Alberta

• In western North America cougar populations are increasing and expanding eastward. Simultaneously, growing human populations are creating new challenges for managers charged with maintaining the viability of cougar populations and their ungulate prey. Information on how cougars respond to human-dominated landscapes and interact with their prey will aid managers in balancing the effects of growing cougar populations with the wishes of growing human populations. Using resource selections functions, I examined cougar responses to roads of varying traffic volumes. Cougars selected rugged terrain presumably to insulate themselves from roads with greater traffic. When assessing impacts of expanding road networks, more attention should be given to roadside topography. Using fine-scale movement and activity data, I examined cougar predatory behaviour. Cougars employed an active stalking style of predation, moving throughout the landscape to locate, stalk, and kill prey. Future models of predator-prey dynamics should consider the cougar’s active style of predation.
